The “Maahir’s Gambit” scenario.

The incorporeality of ghosts is not considered either as immunity to physical attacks or as resistance to them. This ability only gives a chance to dodge an attack and has something in common with the Damage Block ability of minotaurs in the fourth game. In addition, I am interested in the question of whether Soldier's Luck affects the chance of ghosts dodging attacks in any way. I have seen mentions in several sources that this ability of the necromancer reduces the chance of being hit by 15%, but no one knows for sure...
P.S.: DerRauch - all spells hit ghosts, with the exception of Magic Fist - it has physical damage and therefore misses sometimes...
